WATER CALCULATOR
Hand dishwashing water use
Estimate water used during hand dishwashing and its variable water charge.
How this calculation works
Flow × minutes × uses × days gives litres. Divide by 1,000 and multiply by the rate per cubic metre. Count only the time the tap runs, and measure actual flow. Sewer, fixed and heating charges are excluded.
